- Ability to save the key parameters of the mackie control (User A, User B, F1-F2, …)
Sorry to burst your bubble, but Cubase 9.5 is probably already in beta, 4 months to probable release date 
. Keep fantasizing though, it is fun to read.

Just play around with Fruity Loops Steinberg. You’ll see what you’ve been missing out…
And I’m not being cynical, I’m using Cubase for the last 20 years on a daily basis (and I’m a steinberg certified trainer).
To many workflow benefits there that I cannot even begin to count…
Please give us the option of locking the arranger track so that all the other tracks slide up and down beneath it. It would save time.
Reason why I started this thread back in December right after 9 was released 
Being able to create sub-groups within groups/VCA faders would be helpful.
Well we used to be able to switch mono/stereo
And you can hide tracks in mixer separate than project,just uncheck link project mixer link in visabliity section
- bezier, or easy editable curves for automation
- More CC modulation tools (multiply, additive, substractive)
- Workable Auto LFO on Instrument track…
- More horizontal zoom possibilities
I’d like in the new version the ability to customize, add custom actions, or any default preset or/and macros to the mouse right click menu. 
FOLD STEREO TO MONO, for mixing
VST Instrument like Beat Designer (MIDI plugin) WITH direct .wav import on every track, with individual outputs to Cubase mixer (see Beat Designer format, FL Studio pattern …).It s easy for create speed groove drum loops…
